PAUL PUTNAM, WHITE PLAINS, KENTUCKY.

Application filed July 14, 1920. Serial No. 396,068.

To all whom it may concem:

Be it known that I, PAUL PUTNAM, a citizen of the United States,residing at White Plains, R. F. D. 1, in the county of Muhlenberg andState of Kentucky. have invented new and useful Improvements in Churns,of which the following is a specification;

The object of the invention isto provide relatively simple and efficientconstruction of motor driven operating mechanism for churns and simplemeans whereby the speed of movement of the same may be readily andconveniently regulated and wherein the op erating parts are so mountedand supported as to permit of the independent removal and re-positioningof the churn tub or receptacle as may be required in connection with theemptying and re-filling of the same and also to provide means wherebythe movements of the operating mechanism may be readily checked asrequired from time to time during the re-adjustment of the churn tub orreceptacle for the purposes indicated and with these objects in view,the invention consists of the construction and combination of parts, thepreferred embodiment of which is shown in the drawings wherein Figure 1,is a front view of the apparatus.

Figure 2,'is a rear view of the same.

Figure 3, is a side view.

Figure 4, is a plan view.

Figure 5, is a vertical sectional view taken on the plane of the axis ofthe driven head.

Figure 6 is an elevational view of the driving spring and its housing.

The operating mechanism which includes a driving spring 10 and a rotarydriven head 11 with intermediate gear train 12 for communicating motionfrom the former to the latter and a frame 13 consisting of front andrear frame members 14 and 15 and intermediate member 16, the lower endsof the front and rear frame members constituting feet between which isarranged a base 17 constituting a seat for the churn tub or receptacle18. The front and rear frame members include transverse bars 19 and 20and the intermediate frame member includes a frame member 21 whilesupported by the front, rear and intermediate frames below the plane ofsaid frame members is a tank 22 to catch any grease which may drip fromthe operating mechanism and'prevent.

the same from falling into the churn tub or receptacle located in thebase.

The transverse frame members are provided with hearings in which aremounted the operating elements and driving mechanism. The driven head 11is provided with a socket in which is fitted a stem 23 of a dasher 24.preferably having a cross sectionally triangular stock member 25provided in its faces with diagonally disposed slots in which are fittedthe inclined blades 26. The dasher stem is secured in the head 11 bymeans of a set screw 27 or the equivalent thereof.

The motor spring is operatively arranged in a housing 28 and isconnected with the driving gea 29 meshing with the pinion 30 mounted onthe shaft 31 which carries a gear 32 in mesh with the pinion 33 whichthrough a bevelled gear 34 conveys rotary movement 7 to the bevel pinion35 secured to the shaft 36 which carries the driven head. Said shaftpreferably serves to actuate the governor 38 having a worm and gearconnection with the shaft 36 and in the construction illustrated saidgovernor is ofthe centrifugal type and is connected with the sleeve 39carrying friction disk 40 for movement relative to brake blocks 41 tolimit the speed of rotation of the driven shaft. The brake blocks arepreferably carried by an arm or a yoke 42 which is pivotally mountedupon a swinging bracket 43 to which is attached a feed screw 44 threadedin a bracket 45 and provided with a terminal disk 46 for manualoperation. may be adjusted toward and from the plane of the frictiondisk to vary th speed of rotation of the driven head. The arms of theyoke are preferably of yieldable or resil ient material. I 4 Therequired tension is applied to the motor spring by means of a shaft 47provided with a crank handle 50 and carrying a gear 19 meshing with agear 48 which is mounted on a shaft 47 to which one end of the spring 10is connected. Reverse or retrograde movement of the shaft 47' isprecluded by means of a ratchet 51 carried by the shaft and engaged by apawl or dog 52. The driving gear 29 is carried by the housing 28 whichassists the motor spring in the operation of the mechanism and which isConsequently the brake blocks 7 V provided with peripheral ears orprojections 53, while disposed in operative relation with the housing isa rock shaft 5a having a crank 55 adapted to be arranged in engagingrelation with the stop cars 53 when the operating handle 55 is moved inthe direction indicated by the arrow in Figure l.

The lever operates in relation to a ratchet bar 56 and is provided witha dog 57 for engagement therewith. Obviously when the mechanism is to beoperated it is only necessary to shift the lever to a position by whichthe loop or crank of the said shaft is disposed out of engaging relationwith said ears 53 of the spring housing whereas the opposite movement ofthe same will serve to check the rotation of the housing until anotheroperation is required.

When disconnecting the churn tub or receptacle to permit of its removalfrom the frame for filling or emptying purposes, it is only necessary todetach the dasher stem from the socket after having checked the rotarymovement of the head through the means above indicated, and upon thereplacement of the tub Or receptacle and the reengagement of the dasherstem, the resumption of the churning operation may be accomplishedsimply by releasing the motor spring housing. Also it will be obviousthat the speed of movement of the driven head will be regulatable by theadjustment of the yoke which carries the brake blocks as hereiirbefo-reexplained, to suit the conditions under which the churn is beingoperated.

The invention having been described, what is claimed as new and usefulis 1. A power mechanism having a revoluble member by which motion iscommunicated, the said member being provided with spaced peripheral earsthroughout its circumference, a rock shaft having a looped crank armarranged in transverse spanning relation with the periphery of saidmember for engagement with the ears thereof, an operating lever for saidrock shaft, and means: for securing said lever in adjusted positions. 2.A power mechanism having a revoluble housing and actuated springcontained therein tending to move the housing in one direction, theperiphery of the housing being provided with spaced peripheral earsthroughout its circumference and extending transversely across itsperipheral face, a rock shaft having a looped crank arm arranged intransverse spanning relation with the periphery of said housing, and anoperating lever for rocking said shaft to move said looped crank arminto and out of engaging relation with said cars.

In testimony whereof he affixes his signa ture.

PAUL PUTNAM.
